Ti6Al4V (Ti64) alloy is the most used metal material for bone implants because of its good biocompatibility and adapted mechanical properties. Nevertheless, it shows low antibacterial activity, which may favor failure. Addition elements such as copper should avoid this drawback. This work studies addition Cu into a Ti64 matrix resulting in Ti64/xCu composites. Powder mixtures were compacted die...

Additive manufacturing (AM) is the owner of a huge potential as technology in fabricating functional implants, and scaffolds for biomedical applications. AM, which includes 3D printing (3DP) bioprinting, can be solution to produce several needs such scaffolds/implants, tissue or organs, medical devices by combining different biomaterials with nanomaterials. Titanium its alloys Polylactic acid (...

The titanium alloy Ti-407 (Ti407) is a new being considered for single load to failure applications where energy absorption key requirement. This work characterised the deformation and mechanisms of Ti407 in uniaxial tension compression at quasi-static increased strain rates. results are compared with equivalent tests on Ti-6Al-4 V (Ti64) provide benchmark. stress-strain data under each conditi...

Abstract The titanium alloy Ti–6Al–2Sn–4Zr–2Mo–0.1Si (Ti6242) has been deposited for the first time by a directed energy deposition process using wire and arc system— i.e., wire-arc additive manufacturing (WAAM)—with without inter-pass machine hammer peening, its microstructure investigated compared to more commonly used Ti–6Al–4V (Ti64). application of peening—where each added layer was deform...

Titanium alloys are commonly used as biomaterials in musculoskeletal applications, but their long-term efficacy can be limited by wear and corrosion, stress shielding, bacterial colonization. As a promising alternative, bulk metallic glasses (BMGs) offer superior strength corrosion resistance, the influence of chemical composition on bioactivity remains largely unexplored. This study, therefore...

This work presents the results of electron-beam welding commercially pure α-Ti (CP-Ti) and Ti6Al4V (Ti64) alloys. The structure mechanical properties formed welded joints were examined as a function power electron beam. beam was set to P1 = 2100 W, P2 1500 P3 900 respectively. X-ray diffraction (XRD) experiments performed in order investigate phase composition fabricated joints. microstructure ...
